The surface tension of isopropyl alcohol in air has a value of 22.39 units and the surface tension of water in air is 72.86 units.

The answer is "Option B and Option D"

Explanation:

Isopropyl alcohol has an air pressure of 22,39 units with such a water contact angle of 72,86 units.

The melting points of Isopropyl alcohol are higher than water because of the weaker forces between the previously studied.

The flatter meniscus is indeed the isopropyl ethanol so because forces between the particles are smaller.

answer: the rock sample is a sedimentary rock.

explanation:

it is given that:

mass of rock sample, m = 2.7 g

volume of rock sample,

so, density of rock sample will be

since, the density of rock sample is . hence, the rock sample is a sedimentary rock, whose densities varies between .
